Philipp Richter

Prof. Dr. Philipp Richter is a Full Professor and Chair for Astrophysics at the Institute of Physics and Astronomy, University of Potsdam, Germany. He leads the Astrophysics research group at the University of Potsdam, focusing on interstellar and intergalactic gas, galaxy evolution, and observational cosmology. His work involves using absorption spectroscopy in UV and optical regimes to study the circumgalactic medium and intergalactic medium at various redshifts.

Dr. Richter's educational background includes:

• PhD in Astronomy, University of Bonn, Germany (1999)
• Diploma in Physics, University of Bonn, Germany (1997)
• Studies of Physics and Astronomy at Universities of Marburg and Bonn, Germany (1994-1999)
• Abitur, Gymnasium Philippinum, Marburg, Germany (1991)

Dr. Richter's research focuses on the properties of the circumgalactic medium (CGM) around galaxies and the intergalactic medium (IGM) that fills the Cosmic Web. His work employs absorption spectroscopy in the UV and optical regimes to study hydrogen and metal ions in the CGM and IGM at all redshifts. These absorption-line measurements are complemented with emission observations in radio, X-ray, and optical wavelengths. He also utilizes state-of-the-art numerical hydrodynamical simulations to compare with observational results. His research spans galaxy evolution, interstellar medium physics, and observational cosmology.

Analysis of Dr. Richter's recent publications reveals a strong focus on the circumgalactic and intergalactic medium, with particular attention to the Magellanic Stream, galaxy halos, and high-redshift absorption systems. His work combines observational data from instruments like HST/COS with theoretical modeling to understand gas flows in galaxy evolution. Key themes include metallicity patterns, ionization states of gas, and the connection between observed absorption features and large-scale cosmic structure.

Dr. Richter has received several prestigious awards:

• Teaching-Excellence Award, Faculty of Science, University of Potsdam (2022)
• Erskine Fellowship, University of Canterbury, NZ (2018)
• Ludwig-Biermann Award for early excellence in astrophysical research, Astronomische Gesellschaft, Germany (2005)
• Emmy-Noether fellowship/award for early research excellence, DFG (German science foundation) (2003)

As an educator and mentor, Dr. Richter supervises PhD students including Sietske Bouma, Mitali Damle, and Kirill Makan. He teaches a variety of courses in Astrophysics such as fundamental astrophysics, cosmology, galaxy evolution, and interstellar medium as part of the physics/astrophysics bachelor/master programs. He also supervises astrophysics lab courses and seminars, and teaches experimental physics for geo-science students. Dr. Richter has played a significant role in university management, having served as director/deputy director of his department for many years, led committees for appointing professors in astrophysics, and developed the international master program in astrophysics at the University of Potsdam.

Dr. Richter leads the Astrophysics research group at the University of Potsdam, which includes senior scientists, postdocs, and PhD students. The group is involved in various observational projects using telescopes and space-based instruments. They maintain close collaborations with other research institutions and participate in international research initiatives focused on galaxy evolution and the intergalactic medium.
